The final vision in the book of Revelation now makes a little more sense. Not only was the temple the biblical cosmos writ small, the biblical cosmos was the temple writ large. In other words, in the world of the Bible the cosmos is God’s house. As Philo put it, “The whole universe must be regarded as the highest and, in truth, the holy temple of God” (Spec. 1.66). As such the biblical cosmos is a sacred place indeed.— The Biblical Cosmos, page 150 (emphasis original)
The world comes full circle in Revelation. What God intended in the garden gets fulfilled.
